ground.

One object of the present invention is to provide .an improved structuresuch that the forward momentum of the-car will be .utilized in raisingthe same above the ground, thus bringing the car to a gradual stop andeliminating warring and jolting.

A further object is to provide the combination with a trunk .or carriagemounted upon inclines carried \by a frame so that the forward momentumof the automobile onto the carriage moves a-carriage up the inclines ofnovel means for automatically looking or braking the carriage whereby itwill be prevented from retrograde .morement until released by theoperator.

A further ob ect is to provide .the combination with the carriagemounted .upon the inclines, of novel means for limiting the movement ofthe carriage.

With .the foregoing and other objects in view which will appear as thedescription proceeds, the invention .resides in the combination andarrangement of pants and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

wheel supports and illustrating the brake levetr passing through thearms of the sup- P Referring to the drawings in which similar referencenumerals designate corresponding parts throughout the several views, abase frame 6 including longitudinal side beams 7 and cross struts 8, ispivotally secured at its rear end by means of a pivot or allledanchoring device 9, to the floor of a garage or other foundation wherevehicles are to be stored.

The anchoring pivot 9 is located between the beams 7 and is held inplace by braces 10. The front end of the base frame is provided withblocks 11, allowing for the frame to adjust itself to the automobile orvehicle as it passes there-over. In this connection it is to be notedthat longitudinal tie rods 17 extending over to the outstanding arms 16of the beams 7 and terminally connected to the beams, in addition tobracing the beams, afford guiding means against which the vehicle wheelscontact, to force the jack into proper alinement with the vehicle forits subsequent elevation. The tie rods 17 converge at their front andrear extremities and are connected in any suitable manner to the frontand rear extremities of the longitudinal beams 7.

The beams 7 of the base frame are provided with front and rear inclines12 and 13, each of which is composed of a rail 14 with a V-shaped upperedge which is supported in its angular position by an upright or post15. he .angularity of the rails is such that the forward momentum of thevehicle will be totally expended prior to reaching the extreme height atthe upper extremities of the inclines, thus resulting in the gradualstopping of the automobile or vehicle during the period it is beingraised.

Cooperating with the base frame and in clines is the carriage or truck18 which similar .to the base frame, is composed of the longitudinalside beams 19 and cross braces 20. The braces and beams are ofsufiicient size to lend the requisite strength and rigidity to thecarriage. The carriage is movably supported upon the inclines by thewheels 21 which are provided with the notched peripheries 21 engagingwith the upper edges of the rails 14. The wheels are journaled withinthe supports 22, having bifurcations 22 receiving the wheels. Thesupports are positioned beneath and attached to the carriage.

In order to eliminate, to as great a degree as possible, side vibrationand sideswipe due to the automobile contacting with the carriage inother than an axial or medial manner and to limit the reciprocatingmovement of the carriage, a pair of links 23 and 24 are provided at eachside and have their adjacent ends pivoted together, as at 27, and theirremote ends pivoted as at 25 and 26, respectively, to the beams 6 and19. The links are so designed as not to interfere with the normalforward or return motion ofthe carriage but will hold the same againstderailment, it being noted, furthermore, that when the carriage is movedto its lowermost position as illustrated in full lines, in Fig. 1, thelinks 23 and 24 will be straightened out to eliminate the movement ofthe carriage rearwardly,-

and when the carriage is moved upwardly to the dotted line positionillustrated in Fig. 1, the upper links 24 and the upper ends of thelower links 23 will swing against the beams 19 of the carriage 18 toassist in limiting the upward or forward movement ofthe carriage. Inthis connection it is to be also noted that the configuration of thetracks and wheels is such as to prevent derailment and thus provides forthe proper workingof the device.

In order that the automobile will contact with the carriage 19 when runthereonto upstanding abutments 28 are secured upon the front ends of thebeams 19 to contact with the front axle of the automobile which thusmoves the carriage forwardly until such time as the carriage is raisedagainst the axles of the vehicle.

As has been explained, the momentum of the car in ordinary cases is notsufiicient to carry the carriage to its extreme upper position, but toprevent the'possibility of the carriage running beyond the extremitiesof the inclines, the stops 29 are provided at the upper ends of theinclines 13.

In order that the carriage will be locked at intermediate position uponthe inclines, a lever 30 is at each side and has a T-head 31 pivotallyconnected at one end, as at 32, to the beam 19 of the carriage and abrake shoe 34 is pivotally connected to the other or lower end of theT-head 31. The brake shoes 34 extend partially under or adjacent to theWheels 21 and slide'upon the rails 14 so that as the carriage is carriedforward, the brake shoes 34 will not interfere with the free motionthereof. However, when the forward momentum of the vehicle has beenspent in the upward raising thereof, the

carriage and automobile or vehicle will tend to gravitate to the lowerposition and this is checked and prevented by the front wheels 21frictionally engaging the brake shoes 34, the brake shoes wedgingbetween the front wheels and inclines so as to prevent the retrogrademotion of the carriage. The levers 30 project through the front supports22 and are provided with pedals 35 which may be depressed by the foot,resulting in the withdrawal and rearward displacement of the brake shoes34:, carrying them out of wedged contact with the rails and wheels andallowing the carriage to freely gravitate to its lowermost and rearmostposition and returning the automobile or vehicle to its lowered positionupon the ground.

The many advantages inherent with such structures it is thought will bereadily appreciated, among which may be mentioned the fact that theabrupt shock and jar incident to the reaching of the vehicle andcarriage to the uppermost position is entirely eliminated in the presentdevice. The normal forward momentum of the vehicle is suflicient tocarry the carriage to an inter mediate position upon the'inclines, toraise the tires above the ground, and to thus re? lieve the tires whenidle. The braking mechanism will then immediately act and hold thecarriage in such position. Mention is made of the fact that by movingthe brake levers downwardly, the brake shoes will be released from thewheels and rails, allowing the carriage to move rearwardly. However, afurther depression of the brake levers results in their contact with theperipheries or upper portions of the respective wheels 21 and exerts amodified braking action thereon to retard the return of the carriage.
